If you can get the blood supply and innervation to the abdomen down, the rest will follow more easily. An easy way to orient yourself is to use embryological origins as landmarks and go from there.

** Remember that the in the abdomen, both the sympathetic and the parasympathetic fibers are PRE-ganglionic most of the time. **
The sympathetic will synapse in the celiac plexus, the superior mesenteric plexus, or the inferior mesenteric plexus, and then the post-ganglionic fibers will travel to the target organ.
The parasympathetic will not synapse until the target organ.

So for example, derivatives of the caudal foregut will be supplied with blood by branches of the celiac trunk, and will be supplied with sympathetic innervation by the Greater Splanchnic Nerves, mostly T6-T9, and with parasympathetic innervation by the anterior vagal trunk.

What are the specific branches of the celiac trunk that supply the following:
            A. Stomach
            B. Liver
            C. Gallbladder
            D. Biliary ducts
            E. Spleen (*not a foregut derivative)
